National private-industry totals for Nonmetallic Mineral Product Manufacturing (NAICS 327) in 2024, from the U.S. Bureau of Labor Statistics Quarterly Census of Employment and Wages. These are industry-wide totals from a near-complete federal count of employers. They describe the industry overall and are not a measurement of any single establishment or of OSHA enforcement activity. This is the full count of private-sector establishments in the industry, not only those with OSHA inspection records, so it is not directly comparable to the establishment count shown above.

What Nonmetallic Mineral Product Manufacturing (NAICS 327) establishments reported on their OSHA Form 300A summaries for 2024, submitted through OSHA's Injury Tracking Application. These are counts employers reported themselves, not the result of an OSHA inspection, and only establishments required to file under 29 CFR 1904.41 are included, so this is not every employer in the industry and is not directly comparable to the inspection counts above. Deaths are employer-recorded on the form, distinct from OSHA-investigated fatalities. These are case counts, not injury rates; for rates see the BLS Survey of Occupational Injuries and Illnesses.
